Description
Technical field
The present invention relates to a kind of waterproof layer material and preparation method thereof, be specifically related to waterproof binding agent and method of manufacture thereof that a kind of road, bridge floor, tunnel pavement are used.
Background technology
In the past; Some bridge is water layer in the air on surface layer is mated formation; Main rely on that draining is come on slope and weep pipe in length and breadth; Though some bridge floor has also been done waterproof layer, it can't meet the quality requirement, and causes that the bridge surface layer occurs that infiltration, the pull-up of mating formation fall, cement concrete alkali-aggregate reaction, steel bar corrosion, steel plate corrosion and cause that bridge damages.In order to protect the bridge structures to exempt from the infiltration etch, improve the weather resistance of bridge, increase the service life, when the designs of road and bridge and construction, must pay much attention to the waterproof problem of road and bridge.
Abroad, country such as U.S. clearly regulation city and highway bridge must be provided with waterproof layer.China begins to pay attention to the problem that bridge suffers the rainwater etch from the eighties in 20th century, and has carried out many monographic studies with regard to the bridge structure waterproof technique.Think the subject matter that the bridge waterproof exists through researching and analysing: the one, the Bridge Design problem showing that mainly unreasonable the and stressed weak link of the design place of mating formation do not do WATER REPELLENT and the unreasonable problem that causes of bridge structure waterproofing design; The 2nd, the water-proof material problem mainly is to lack the special-purpose water-proof material of bridge; The 3rd, on the construction link, the waterproof construction quality does not form unified working specification and standard for acceptance as yet, lacks the bridge construction waterproof construction troop of specialty.
Domestic in the bridge of newly-built or transformation, the way of waterproofing work is between the skeleton construction of bridge or steelwork and asphalt concrete pavement layer, to add waterproof layer.Present domestic water-proof material is main with flexible waterproof material, mainly contains road and bridge special-purpose water-proof coiled material, waterproof paint, waterproof and sealing material etc.Waterproof roll high thermal resistance, impermeability, stability to aging, anti-ly press against brokenly, high temperature shearing resistance, anti-low-temperature cracking all be superior to waterproof paint, but be prone to bulge during the coiled material construction and caused slip; Waterproof paint has characteristics such as easy construction, cost is low, the road pavement planeness is less demanding, cohesiveness is good, but tensile strength that most coating is filmed and unit elongation are lower, and relatively poor to the flexibility of bridge deformation, rigidity is filmed then poorer.
In addition, the solvent welding agent in the market generally contains aromatic hydrocarbon solvent harmful, environmental pollution, and threat production and workmen's is healthy.
Summary of the invention
The object of the present invention is to provide a kind of waterproof binding agent, this waterproof binding agent is good, environmentally friendly as its mechanical property of waterproof layer of road, bridge floor and tunnel pavement.
